Publicly available exploit code does not exist at this time," Randori said. Exploitation of the vulnerability chain has been proven and allows for remote code execution on both physical and virtual firewall products. "The vulnerability chain consists of a method for bypassing validations made by an external web server (HTTP smuggling) and a stack-based buffer overflow. Randori exploited Palo Alto Networks PA-5220, including PAN-OS 8.1.16 and PAN-OS 8.1.15. Portnoy said his team was able to gain a shell on the affected target, access sensitive configuration data, extract credentials and more while moving laterally from there and gaining visibility into the internal network. The exploit gains root privileges - complete control over the device - and can execute arbitrary code. By November 2020, his team discovered CVE-2021-3064, began authorized exploitation of Randori customers, and successfully landed it at one of their customers - over the internet - not just in a lab. "On virtualized devices (VM-series firewalls), exploitation is significantly easier due to lack of ASLR, and Randori expects public exploits will surface," Portnoy said.Īccording to Portnoy, in October 2020, his team was tasked with researching vulnerabilities with the GlobalProtect Portal VPN. Portnoy said that exploitation is difficult but possible on devices with ASLR enabled, which appears to be the case in most hardware devices. We have found the overall security posture of the affected devices to be on par with other vendors in the space." Complex products such as PAN firewalls include protections that make this process difficult regardless of the vulnerability. "As is the case with many closed-source products, simply setting up an environment in which to develop an exploit is challenging.

This process allowed us to identify the components an attacker would have to exploit in order to compromise the device," Portnoy explained. We then devoted resources into assessing the attack surface of the firewall itself in a lab environment. Randori believes the best way to identify potential points of attack is to assess the attack surface. "Once an attacker has control over the firewall, they will have visibility into the internal network and can proceed to move laterally.
#Globalprotect portal update
Palo Alto has released an update that patches CVE-2021-3064 after being notified about the issue in September.Īaron Portnoy, principal scientist at Randori, told ZDNet that the original catalyst for their research into Palo Alto Networks firewalls was identifying its presence on customer perimeters. It is used by a number of Fortune 500 companies and other global enterprises. The issue affects multiple versions of PAN-OS 8.1 prior to 8.1.17, and Randori said it found numerous vulnerable instances exposed on internet-facing assets, in excess of 70,000 assets. The zero-day - which has a severity rating of 9.8 - allows for unauthenticated, remote code execution on vulnerable installations of the product.
